Semiconductor memory has leakage controller to reduce charge transfer between storage circuit and bit line, before reading data from memory cell and storage circuit to generate read voltage for read circuit, based on stored data

摘要

A controller controls charge transferability of charge transferring circuit to transfer charge read out from a storage circuit, based on change in bit line voltage. A leakage controller reduces charge transfer between storage circuit and bit line, before reading data from the cell. The storage circuit generates read voltage for read circuit, based on logical value of the stored data.
